IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 34,354, dated February11, 1862.

.To all whom t may concern,.-

Be it known that we, O. D. EGKERSON and OVATSON, both of Middleburg, inthe county of Schoharie and State of New York, have invented a new anduseful Improvement in Wa ter-Elevators; and we do hereby declare thatthe following` is a full, clear, and exact description of the same,reference being had to the accompanying drawings, making a part of thisspecication, in which- Figure l represents the Water-elevator by a frontView. Fig. 2 represents the same by a transverse section taken at theline ocx, Fig. l. Fig. 3 is a transverse section of the windlass orcrankshaft and drum. Fig. 4 represents a transverse section of the drum,taken at the line y y, Fig. 3, showing the manner of fastening thebucket-strap thereto.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to that class of water-elevators which areemployed for drawing water from wells by means of a bucket suspended bya cord or strap from a windlass, the bucket having a water-way in thebottom to cause it to lill as it descends into the water in the well,and a hinged valve to close the said water-way when the bucket is filledto prevent the water therein from escaping through the bottom whilebeing drawn, the bucket being tilted by suitable mechanism when at theproper height to discharge the water into a spout in the well-curb.

The invention consists in the manner of fastening the cord or strap bywhich the bucket is suspended to the drum on the windlass orcrank-shaft, as will be hereinafter fully explained.

.o enable others skilled in the art to fully understand and constructour invention, we will proceed to describe it.

A represents a curb box, which is constructed, in the usual man ner, offour uprights boarded part way up on the outside and forming a squareboX., which is furnished on the inner and front sides with a trough B,having an opening a in the bottom to allow the water discharged thereinfrom the bucket to run out. On the top of the uprights, and which serveto strengthen the curb-box, are two pieces of scantling C D, which areplaced parallel with each other and mortised into or otherwise securedto the uprights and support the elevating mechanism.

E is a windlass or crank-shaft, which is located near the back of thecurbbox and journaled in boxes b l), which are secured on top of thescantling by screws or bolts passing through them into the scantling.

In the middle of the crank-shaftE, between the boxes b Z), a flangeddrum F is rigidly secured against a shoulder by projections c c, whichare cast upon the shaft and extend longitudinally thereof. Theseprojections enter corresponding grooves in the drum, and thereby preventthe drum and shaft from independent movement. The drum is securedagainst lateral movement in one direction by the shoulder lm on theshaft and in the other direction by a key n, which is driventransversely through the shaft. At one pointin the peripheryT of thedrum, between the fianges, a groove u is made therein parallel with thecrank-axle, which, in connection with a pin or bolt s, passedtransversely through the flanges and drum inside of t-he periphery ofthe latter, serves to secure one end of the strap by which the bucket issuspended and elevated, so that the strap J will wind even and true uponthe drum. At each extremity of the said groove a cavity V is formed inthe drum, which cavities assist in making the fastening of the strap tothe drum more secure. To fasten the strap J, the end is placed on thedrum and pressed in the groove u, so as to sink the sides into thecavities V at each end. The pin s is then driven through holes passingtransversely through the iianges over the strap, so as to confine thestrap between the pin and bottom of the groove, and thus secure thestrap by compression, the sides of the strap which are sunk into thecavities serving' to make the4 fastening more secure.

The bucket H is made of the usual shape, and suspended from the strap Jby a bail g, attached by a swiveled connection on opposite sides of thebucket about onethird of the distance down from the top.

In the bottom ofthe bucket an opening is made, through which the waterenters to till the bucket when lowered into the well. This opening isclosed on the inside by a valve o, which ishinged at one side of theopening to the bottom and acts by gravity to close the opening when thebucket is raised out ofthe Water in the Well.

Attached to the front and back side of the bucket, and at right anglesto the bail at top, are hooks j, one of which, when the bucket iselevated to a certain height, catches under a tilterp, hinged onopposite sides of the trough, to tilt the bucket, and thus cause it todischarge its contents into the trough.

The crank-shaft near the crank-side is provided With a ratchet-Wheel q,which is east with a drum on one side, against the periphery of whichthe hinged lever I acts, and by friction alone serves to give a personperfect control over the descent of the bucket. A pawl 7c, hinged to thescantling D, engages with the teeth of the ratchet-Wheel, and therebyprevents Ithe crank-shaft from turning backward except when it isdesired to lowerA the bucket into the well.

When the bucket is let down into the Well, the Water raises the valveand fills the bucket, and on the bucket being raised the valve closes inconsequence of the pressure of the Water uponit, assistedby its ownWeight, and remains closed until the bucket is elevated, discharged, andagain lowered into the Water in the Well.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

The combination of the pin s With the flanged drum F, groove u, andcavities V, When arranged to operate in the manner and for the purposedescribed.
